Displaying results for long lists is messy.

[gnublet]

For example, type [1,2,3,4]*100 in the input box and press Ctrl+Enter you will see a long vertically formatted list:

[1,
 2,
 3,
 4,
 1,
 2,
 3,
 4,
 1,
 2,
 3,
 4,
...

This can be improved by displaying the list on multiple columns like ls.

Thanks, this is already tracked as ipython/ipython#8741 (the way lists display is part of IPython, not the notebook). Unfortunately we have not yet found a good general fix that doesn't mess things up for things like lists of lists or lists of dicts.
